In order to collect further information on issues related to tobacco control which should be addressed in future tobacco control measures in Hong Kong, COSH commissioned School of Public Health (SPH), the University of Hong Kong (HKU), to conduct a third wave of the survey (2014/15). The current survey sought to use the Hong Kong data to update information on the prevalence of SHS and active smoking and its health effects, use of E-cigarettes, awareness of smoking cessation services and to identify the level of public support for current and future tobacco control measures as well as estimating the impact of existing policies.
